Daxx's Burning Barrel

You channel arcane energy into one firearm that you can see within a range of 60 ft, you enchant the barrel of the firearm with fire magic, causing the ammunition fired from it to catch fire. Until the spell ends, you deal an extra 1d8 fire damage to any target you hit with the weapon. If the weapon isn’t magical, it becomes a magic weapon for the spell’s duration.

At Higher Levels. Increase the damage dealt by 1d8 for each level spell slot above 1st.
